1Rotate insecticides with a different mode-of-action group number, and do not use products with the same mode-of-action group number more than twice per season to help prevent the development of resistance. For example, the organophosphates have a group number of 1B; insecticides with a 1B group number should be alternated with insecticides that have a group number other than 1B. Mode-of-action group numbers for insecticides and miticides (un=unknown or uncertain mode of action) are assigned by IRAC (Insecticide Resistance Action Committee).
2 Ratings are as follows: I—Do not apply or allow to drift to plants that are flowering, including weeds. Do not allow pesticide to contaminate water accessible to bees, including puddles. II—Do not apply or allow to drift to plants that are flowering, including weeds, except when the application is made between sunset and midnight if allowed by the label and regulations. Do not allow pesticide to contaminate water accessible to bees, including puddles. III—No bee precaution, except when required by the label or regulations. For more information about pesticide synergistic effects, see Bee Precaution Pesticide Ratings.
3 Restricted entry interval is 7 days for cotton scouts.
4 Determined by amount of yearly rainfall; see label.
5 Do not apply after bolls open.
6 Brood poison at lower doses.
